The Nemo Arms 48-position gas block is available on the XO and the Omen models starting mid-year in 2023.  



For unsuppressed shooting, we recommend starting the gas block at about 25 clicks from fully closed position.

  1. Turn the adjustment knob clockwise until it’s fully closed
  2. Turn the adjustment knob counterclockwise 25 clicks
  3. Test the setting by firing a few rounds and watch where your casings are ejecting.  
      • If you notice them ejection to the front of the rifle, there is too much gas
      • If the casings are ejecting to the rear of the rifle there is not enough gas
      • Ideally you want the casings to be ejecting straight out perpendicular to the rifle, at shooter’s 3 o'clock.
  1. We recommend adjusting 3 clicks at a time (clockwise for less gas, counter-clockwise for more gas)

 

For suppressed shooting, we recommend starting the gas block at about 5 clicks from fully closed position.

  • Test fire at this setting and adjust per the notes above.


The 48-position system allows you to make fine-tunning adjustments depending on your environment, ammunition, or smoother cycling. 

  • If you are shooting lighter grain ammunition, or as carbon accumulates in your rifle, you may need to add gas to maintain proper cycling.
  • If rounds are cycling properly, reducing the amount of gas can reduce recoil.  
  • We recommend adjusting 3 clicks at a time.
